Dogs are difficult to take care of还是to be taken care of?
There are twenty trees to to plant还是be planted?
We have twenty trees to plant?还是to be planted?
为什么?这是什么知识点?

前两个to take care of /to be taken care of 还有to plant /to be plant 都可以,后面的的通常都是to plant 因为句中出现了动作的实施者.
如果有具体语境的话,比如说We have twenty trees for them ...后边就必须用to be planted .如果动作是由自己完成就不必使用被动式.
其实就是看动作的实施者是不是说话的人.如果是让别人来做的话就得用被动式.再举个例子I've got some clothes to be washed .就可以暗示你是把衣服拿给别人去洗了
